N.T. Wright rejects the argument from “progress” in favor of female bishops:

It won’t do to say, then, as David Cameron did, that the Church of England should “get with the programme” over women bishops. And Parliament must not try to force the Church’s hand, on this or anything else. That threat of political interference, of naked Erastianism in which the State rules supreme in Church matters, would be angrily resisted if it attempted to block reform; it is shameful for “liberals” in the Church to invite it in their own cause.

I love that “liberals” is in scare quotes, and lest you think that Wright opposes female bishops:

The other lie to nail is that people who “believe in the Bible” or who “take it literally” will oppose women’s ordination. Rubbish.

Exactly right. The scriptures themselves provide the strongest argument in favor of ordaining women, and to base our arguments on cultural norms is to cede the hermeneutical high ground to the patriarchy.
